The present invention relates to a combined lubricating means and sidestop for railway car journal bearings and has particular reference to animproved retainer pan by means of which an absorbent lubricator pad ismaintained in intimate contact with the rotating journal within ajournal box, and also by means of which lateral side sway of the journalrelative to the journal box is effectively prevented.

The lubrication of railway car journal bearings has long presentedproblems in railway operation. One method of lubrication has entailedthe use of oil-soaked waste packed into the journal boxes in such amanner that the waste makes contact with the underneath side of thejournal so that the lubricant contained within the journal box isbrought into contact with the journal by a capillary or wick action andis carried by the rotation of the journal into contact with the bearingelement or brass which normally seats on the upper portion of thejournal. Due to the fact that hot-boxes frequently result from theinclusion of strands of packing Waste drawn between the journal and thejournal bearing by virtue of the rotation of the journal, or byabrasives and other foreign matter in the packing, car journallubrication has been improved by the use of pads or similarlubricant-supplying devices which are used instead of Waste, these padsbeing yieldingly forced into contact with the underneath side of thejournal by underslung pad-retainers or sealed reservoirs which partiallyoncompass the journal and serve to maintain various types of absorbentpads in contact with the journal. Such retainers and reservoirs areinvariably suspended from the journal hearing or brass, or they aremaintained in an elevated position above the curved bottom of thejournal box by resilient supports which rest on the bottom of thejournal box. Most of these retainers are specially designed toaccommodate special types of absorbent pads. All of them serve the solefunction of maintaining a supply of lubricant in intimate contact withthe underneath side of the journal.

Retainers of this general character are possessed of numerouslimitations principal among which is the difiiculty of inserting theretainer into the journal box and removing the same therefrom, as wellas the difliculty of introducing and removing the replaceable padsassociated with such retainers into the annulus existing between thejournal and pad retainer. Many such devices must be inserted into thejournal box through the inner end thereof and this necessitates axlepulling operations. Additionally, many of these pad retainers requirethe use of special fastening devices such as screws, clips and the likewhich are diflicult to apply due to their inaccessibility. Still otherdevices of this nature must be specially contoured to accommodate theshape of a given journal box, of the journal bearing within the box, andof the journal itself.

The present invention, insofar as its lubricating potentialities areconcerned, is designed to overcome the abovenoted limitations and othersthat are attendant upon the use of conventional absorbent pad retainingdevices and, toward this end, it contemplates the provision of arelatively simple pan-like retainer which is formed of sheet metal andwhich is capable of being introduced into the atent journal box from theouter end thereof, i.e. through the usual lid-covered opening providedat such outer end. The invention further contemplates a pan-likestructure of this character which is made up of sheet metal possessing aconsiderable degree of resiliency and which is capable of beingcontracted manually so that it will readily pass through the journal boxopening without interference, after which it may be caused to partiallysurround the journal and be released so that it will snap into operativeposition, so to speak, and engage the side walls of the journal boxwhere it will be, at least in part, frictionally held in position andpresent an open front through which an absorbent pad, a series of suchpads, or other lubricant confining means may be readily inserted andwithdrawn.

Apart from the matter of journal lubrication, the present invention isconcerned with the prevention of journal side sway within the journalbox. The effect of journal side sway has long been noted in connectionwith railway car operation and it has been found that due to the swayingmotion of a railway car, which frequently is a cumulative matter in thatthe amplitude of sway builds up as the car wheels rebound in oppositedirection from their confined relationship on the tracks, the journalhearing or brass will ride upwardly on the filleted portion of the axlebetween the journal and the dust guard hearing surface, thus causingdamage to the hearing or to any liner which may be associated with thesame. Similarly, at the outer end of the axle, the hearing or liner mayride upwardly on the usual end collar and cause damage to the hearing orliner. To obviate this difliculty, various limit stops have beendevised, these limit stops being applied to the side walls of thejournal box at an elevation approximately at the horizontal midplane ofthe rotating journal so that when excessive side sway takes place theywill be engaged by the rotating journal and the extent of such side swaylimited thereby. While such devices may be satisfactory in operation,the fact that they are anchored to the side walls of the journal boxpresents numerous problems. Where such devices are bolted to the journalbox side walls, they fail to meet recent A.A.R. requirements in thatthey necessitate the existence of bolt holes in the journal box sidewalls. Where the fastening means is entirely internal, the use of thetools for their application to the journal box side walls and for theirremoval therefrom is made diflicult, if not precluded entirely. Thus,after these limit stops have become worn beyond further usefulness, thematter of replacement thereof necessitates at least partial separationof the journal and journal box.

The present invention is also designed toovercome the above-notedlimitations that are attendant upon the use of fixed journal stopswithin a journal box and, toward this end, it is contemplated that theresilient sheet metal pad-retaining pan or holder briefly outlined abovebe also employed for maintaining a pair of journal stops in positionagainst the journal box side walls. The journal stops are removably butfixedly secured to the distal edges of the generally U-shaped sheetmetal retainer so that they will be held by these edges of the retainerelfectively against the journal box side walls in their properdiametrically opposed relationship relative to the rotating journalwhere they may assimilate excess side sway of the journal. Novel meansare provided for removably retaining the stops in position in the sideedge regions of the retainer so that they may be removed for purposes ofinspection or replacement without disturbing the retainer or padassociated therewith. The retainer and journal stops are so designed.that after the retainer has been operatively introduced into the journalbox as previously described, and released, the

side edge regions of the retainer will move outwardly against the sidewalls of the journal box and afford sumcient clearance for easyinsertion of the journal stops into position between the journal and theside walls of the journal box, as well as for removal thereof whendesired. Additionally, interlocking means are provided between theretainer and side walls of the journal box, as well as between thejournal stops and theside walls of the journal box, for effectivelyholding the entire assembled unit including the sheet metal retainer andits associated journal stops against longitudinal shifting movementwithin the journal box. The provision of a combined lubricant reservoirand side stop for railway car truck journal bearings of the characterbriefly set forth above being among the principal objects of theinvention, numerous other ancillary objects and advantages will becomemore readily apparent as the following description ensues.

In the accompanying three sheets of drawings forming a part of thisspecification one illustrated embodiment of the invention has beenshown.

Referring now to the drawings in detail, and in particular to FIGS. 1and 2, the combined lubricating device and journal side stop of thepresent invention is shown as being operatively applied to the axlejournal 10 of a conventional wheel axle 11 within the journal box 12 ofa railway car truck. The journal box 12 selected for illustration hereinis of standard construction and is shown as being integrally cast withend portions 14, 16 of a truck side frame. The journal box 12 isprovided with an outer end opening 18 adapted to be closed by the usualhinged journal box lid 20 which is pivotally carried on a pin 22supported between a pair of lugs 24- formed integral with the journalbox casing. Spring means 26 is provided for maintaining the lid 20 ineither its fully opened or its fully closed position.

The inner end of the journal box 12 is provided with an opening 30through which the axle journal 10 projects inwardly of the journal box.The journal box is provided with the usual dust guard slot 32 carrying adust guard 34 which bears against a dust guard bearing 36 of the axle 11to exclude dust, dirt or other foreign material from entering thejournal box through the opening 30.

A journal bearing member or brass 40' overlies the axle journal 10 andis provided with a liner 42 of babbitt or the like which partiallyencompasses the axle journal and rests thereon. A wedge member 44 isinterposed between the bearing member or brass 40 and the top of thejournal box 1'2 and has an end 46 hearing against a lock shoulder 48formed integrally on the journal box.

In order to minimize axial movement of the journal relative to thebearing 40, the inner edge region of the bearing member is rounded as at50 and follows the flared inner end of the journal 10 where the lattermeets the dust guard bearing 36, while the forward end face 54 of thebearing 40 opposes a rearwardly facing shoulder 56 of the end collar 58which is provided on the extreme outer end of the journal 10. Thespacing of these various parts is such as to permit only a limiteddegree of axial shifting movement of the bearing member 40 on thejournal 10.

Although the combined lubricant reservoir and side stop of the presentinvention is capable of use with a large variety of journal boxes, i.e.journal boxes having varying shape characteristics, the assembly isparticularly well adapted for use in connection with journal boxes whichare formed with integral opposed side lugs 60 (FIG. 2) which are cast onthe side walls 62 of the journal box, and which are also formed withrecessed portions 64 in the form of side wall indentations in the upperregions of the side wall 62.

The details of the journal box structure 12 thus far described arepurely conventional and no claim is made herein to any noveltyassociated with the same, except insofar as these details cooperate withthe improved combined lubricant reservoir and side stop of the presentinvention and the nature of which will be set forth in detail presently.

As best seen in FIGS. 6 and 7, the combined lubricant reservoir and sidestop of the present invention is in the form of a composite assembly ofparts which has been designated in its entirety at 70 and which includesan arcuate sheet metal retainer or pan 72, and a pair of journal stops74 the latter being removably secured to the pan 72 by certain fasteningelements which have been shown in detail in FIG. 7. As has beenexplained above, the journals and journal boxes of the prior art havebeen lubricated by packing the bottom of the journal box with oil soakedwaste which contacts the underneath side of the journal so that therotating journal will wipe a film of lubricant from the waste tomaintain lubrication between the bearing brass, its liner and thejournal. According to the present invention, the retaining pan 72 isadapted to receive therein a suitable absorbent pad 76 (FIG. 2) which isdeformed thereby so as to fit closely around the underneath side of thejournal to the end that the journal hearing or brass will at all timesbe supplied with proper and adequate lubricant which is conducted to thejournal and forced into intimate contact with the same by the wick orcapillary action ordinarily associated with such absorbent pads.

The reservoir-forming retainer 72 is arcuate in transverse cross sectionand is approximately semi-cylindrical. This pan 72 is described hereinas being formed of flexible, resilient sheet metal although otherflexible sheet material is contemplated as for example any one of anumber of suitable plastic materials such as neoprene, or the like whichpossesses the necessary degree of resiliency to permit it to function inthe journal box in the intended manner. As best seen in FIG. 2, thearcuate pan 72 is adapted to be seated on the bottom of the journal box12 and closely follow the contour of the journal'box bottom and thelower regions of the side walls 62.

Still referring to FIG. 6, the inner and outer arcuate edges 76 and 78of the trough-shape pan 72 are rolled radially outwardly and reversedupon themselves to not only reinforce the edges and lend additionalspringiness to the structure, but also to protect the fingers of anoperator against damage during installation or removal of the assemblyin and from the journal box respectively, as

well as to facilitate insertion of the absorbent pad 76 into the openannulus existing between the pan 72 and underneath side of the journalafter the assembly is installed. The upper longitudinal edge regions ofthe general U-shaped pan 72 terminate in longitudinally extendingchannels or troughs 80 which are afforded by bending the metal of thepan inwardly as at 82 (FIG. 8) upwardly as at 84 and outwardly as at 86,this latter portion providing a flange which terminates in an outwardlyfacing edge 88. The channel portions '80 are commensurate in crosssectional size and shape to the cross sectional size and shape of thelugs 60 so that when the assembly 70 is installed within the journalbox, the lug 60 will extend into the channels 80 as shown in FIG. 2,while the lower regions of the pan will closely follow the curvedcontour of the lower regions of the journal box. Because of the rollededges 74, 76, a thickness of metal adjacent the a front and rear edgesof the pan serves to maintain the main body portion of the pan slightlyspaced from the curved bottom wall of the journal box, thus affording asmall or thin annular clearance 90 (FIGS. 1, 2 and 8) between the panand journal box. The base portion of the U-shaped pan 72 is formed withan elongated hole or slot 92 therethrough (FIG. 6) which, in conjunctionwith a series of four holes 94, appropriately spaced along the bottomregion of the pan, enable the lubricating oil which is supplied to thejournal box to pass through the pan and become absorbed by capillaryaction in the absorbent pad 76. An additional pair of holes 96 areformed in the forward regions of the pan 72 on opposite sides of thevertical plane of the pan and function in the manner of pulling eyeletsto receive therein one end of a suitable hook or the like associatedwith a pan-removal tool. The small clearance 90 between the body portionof the pan 72 and the inside face of the journal box enables the hookportion of the tool to be passed completely through the holes 76 forengagement with the edges of the holes prior to the application ofpulling force to the pan.

The absorbent pad 76 may assume various forms and no claim is madeherein to any novelty associated with the same. Various other forms ofpads may be employed if desired and, in certain instances, it iscontemplated that the semi-cylindrical annulus between the pan 7-2 andthe underneath side of the journal may receive therein a multiplicity ofabsorbent pads or it may be simply packed with cotton waste or othersuitable filler material. Preferably however a single pad such as theillustrated pad 76 is employed. This pad includes an outer covering orjacket of relatively thick felt sheet stock of rectangular design whichis folded upon itself as at 100 to provide an upper pad side or section102 and a lower pad side or section 104 (FIGS. 1 and 2). The edgeregions of the felt material are stitched together as at 106 thusproviding an open pocket 108 within the structure adapted to receivetherein an inner pillow 110 including a fabric covering 112 and a core114 of absorbent material which may be sponge rubber, asbestos or otherfibrous material. The stitching 106 may extend inwardly along the frontedges of the pad to leave a small opening 116 at the front of the pocketand through which opening a canvas or other flexible pulling strap 118may pass. The strap 118 is suitably afiixed to the pillow and it isprovided with a metal eyelet 120 designed for cooperation with asuitable hook or tool for pad removal operations as will be describedpresently.

The details of the journal box and its associated pan structure 72 thusfar described have been set forth specifically in connection with thenovel lubricating means of the present invention. The retaining pan 72also functions properly to maintain the journal stops 74 in theircorrect diametrically disposed relationship on opposite sides of thejournal and against the side walls 62 of the journal box so that thesestops will find reaction support on these side walls and assimilate anyshock which may be transmitted thereto during side sway of the journalrelative to the longitudinal axis of the journal box.

Accordingly, the fastening means which has been illustrated in detail inFIGS. 6 and 7 serves removably to retain the two journal stops 74 inposition along the upper side edge regions of the U-shaped pan 72. Asclearly shown in FIG. 7, the upper outwardly turned portion 86 of eachchannel is formed with a pair of spaced elongated rectangular slots 122and 124 respectively, the slot 122 being designed to receive therein ahook lug 126 and the slot 124 being designed to receive therein a lug128 formed on the underneath side of each journal stop 74 when the stopis mounted in position over the outwardly turned portion or flange 86 atthe extreme upper edge of each side of the pan 72. Each stop 74 is inthe form of a metal body, preferably formed of brass, and which isgenerally of a configuration conforming to the cross sectionalconfiguration of a structural eye beam having enlarged front and rearhead portions 130 and 132 respectively, and a relatively thininterconnecting web portion 134. The depending lugs 128 and 126 areformed on the head portions 130 and 132 respectively, both lugs beingformed on the underneath side of a downwardly facing shoulder 136occasioned by the provision of a groove or recess 138 formed in thelower outside edge of the journal stop 74. The inside face of thejournal stop 74 is curved as indicated at 140 in conformity to thecurvature of the cylindrical journal 10, these curve faces beingdesigned for contact directly with the journal when the journal,duringside sway exceeds a predetermined displacement.

Each stop member 74 has associated therewith a sheet metal shim retainer(FIGS. 6, 7 and 8). Each shim retainer 150 has a fiat side 152 whichextends along the outside faces 154 of the enlarged heads 130 and 132. Apair of inturned ears 156 and 158 straddle the front and rear ends 160and 162 respectively of each stop while an elongated inturned flange 164underlies the downwardly facing shoulder 136 of the cutaway recess 13 8so that the shim retainer 150 as a whole closely hugs three sidesurfaces of the associated journal stop 74. Clearance notches 166 areprovided in the flange 164 at the front and rear ends thereof toaccommodate the downwardly extending lugs 125 and 128 when the parts areassembled. A rectangular clearance notch 170 accommodates the adjacentside wall indentations 64 on the side wall 62 of the journal box 12 whenthe assembly 70 is operatively installed and in its final positionwithin the journal box.

Still referring to FIGS. 6 and 7, a small sheet metal keeper .180 isprovided for the purpose of retaining each journal stop 74 in itsproperly seated position on the upturned flange portion 86 of thechannel 80. This keeper is generally of U-shape configuration andincludes a lower arm 182, an upper arm 184, and a connecting verticalbight portion 186. The keeper is adapted to straddle the front end face160' of the journal stop 74 with the arm 182 underlying the inturnedflange 164 of the shim retainer 150, a notch 188 being provided in thearm 182 to clear the depending lug 128 for-med on the underneathshoulder 136. The upper arm 184 overlies the upper face of the head 130and it is provided with an upturned ear 120 which fits against theforward face of a small rectangular lug 192 which projects upwardly fromthe upper face of the head 13!]. A cotter pin 194 is adapted to extendthrough holes 196 and 198 which are drilled in the ear and lug 192respectively to maintain the keper 180 in position on the head 138.Although no shims have ben illustrated in FIG. 7, it is contemplatedthat when necessary, one or more shims such as the shims shown at 200 inFIGS. 6 and 8 may be inserted between the inside surface of the largeface 152 of the retainer 150 and the outside face 154 of the associatedjournal stop 74. Each shim is in the form of a flat rectangular sectionof shim stock of suitable thickness having a rectangular cutaway portion202 providing a clearance notch in exact register with the clearancenotch 170. An upstanding post 210 (FIGS. 2, 6 and 7) is formed on theupper face of the head 128 of each journal stop 74 and, when the entireassembly 70 is in its operative position within the journal box, thispost 110 is adapted to fit behind the adjacent recessed portion of thejournal box side wall 62 in direct opposition to a rearwardly facingshoulder Z12 existing by virtue of the recessed portion 64 as clearlyshown in FIG. 4 to limit the forward movement of the assembly within thejournal box.

Installation of the combined lubricant reservoir and journal stop 70within a journal box such as the box 12 may readily be effected withoutthe use of tools. Prior to application of the two journal stops 74 tothe side edges of the sheet metal reservoir pan or retainer 72, the panis collapsed by applying inward pressure to the sides thereof, thusdecreasing the curvature of the unit and bringing the side edges thereofsufficiently close together that the unit may be inserted through theouter journal box opening 18 as shown in dotted lines in FIG. 5. Byinclining the thus partially collapsed pan 72 at an angle ofapproximately 54 relative to a horizontal plane, the rear rolled edge 76of the pan may be slid, so to speak, into position beneath the journalend flange 58. The pan may then be pushed further inwardly of thejournal box chamber while at the same time it is gradually straightenedout or levelled so that its axis tends to assume a horizontal positionwith the two channel portions 80 moving into horizontal register withthe two opposed side lugs 60 which are integrally formed on the insideface of the journal box side walls 62. After the pan 72, still in itscollapsed condition, has been forced rearwardly to such an extent thatthe vertical post 210 passes the adjacent recessed portion 64 of thejournal box 12 (FIG. 4), the pan may be released so that the sidesthereof will spring outwardly under the influence of the inherentresiliency of the sheet metal of which the pan is formed. The side lugs60 will then enter the channels 89 and assume positions within thechannels between the slots 122 and 124. The rolled edges 74 and 76 ofthe pan will bear against the curved bottom wall and the vertical sides62 of the journal box, while the vertical post 210 will fall behind theshoulder 21?. (FIG. 4) so that the pan assembly is securely held withinthe journal box chamber against tilting movement in any direction andaganst axial shifting in either direction.

After the pan 72 has thus been released and allowed to spring into itsfinal or home position within the journal box chamber, the two journalstops 74 are applied to the upper side edge regions of the pan.Application of either stop 74 is made by inserting the same endwise intothe journal box through the outer opening 8-1? and then causing thedepending hooked lug 125 to enter the slot 122 in the upper flange 86 ofthe channel 80 as clearly shown in FIG. 5. Thereafter, the rear or outerend of the stop 74 is lowered so that the depending lug 128 enters theslot 124 in the flange 86. Finally, the sheet metal keeper 186 isapplied and fastened in position by the cotter pin 194 in the mannerpreviously described and the assembly is then complete.

Withdrawal of the combined lubricant reservoir and journal stop 7i; iseffected by a reversal of the various installation steps set forthabove, the holes 96- in the lower and outer regions of the pan 72 beingemployed in conjunction with a pulling hook or other suitable tool aspreviously described.
